SHIPPING CASE..

Application filled April 16, l923. Serial No. 632,558.

I To all whom t may concern.

Be it known that ll, HERBERT R. Bmss, a

citizen of the United States, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Shipping Cases, of which the following is a specification. This invention relates to a method for sealing fiber shipping cases and has for its object an improved fiber shipping case which is so desi ed and calculated as to avoid some of t e objections now urged against fiber shipping cases which are sealed at the center. There are now on the market, fiber shipping cases which are sealed either by gluing the flaps together at the center with a sil1cate glue or by a sealing tape. The joint here is ordinarily a butt joint. There are also on the market shipping cases sealed at the center by an overlap wire-stitched joint. These have been described and claimed in my prior applications, No. 514,788 and No,- 501,620. I have also described and claimed in a co-pending application No. 632,556 a method of coupling up abutting flaps at the center by wire-stitching, which as far as I know, has never heretofore been done.

However, some shippers, especially shippers of very heavy articles, object to the center sealing for the reason that the cases are sometime picked up by employees at the ends of the cover wings and they sometimes tear here under such handling. It is the object of the present invention to eliminate this objection and make a shipping case which has a makimum strength at the sealing end.

In the drawings:

Fig. 11 is a plan view of the body blank on a reduced scale.

Fig. 12 is a plan view of the end blank on a reduced scale.

Referring toF ig. 11, the body blank will be seen. It comprises a bottom, cz, two sides b, b, and a top, c. This top'is substantially of the same width as the bottom. In'the ordinary shipping case body blank, the cover wing is usually only half the width of the bottom or a little more than half to permit the slight overlap. Here, however, the top wing is substantially the width of the case. On the opposite endof the blank T provide a narrow cover flap d.

The end blank is shown in Fig. 12, and comprises a main end wall e, with three fastening flaps f at the bottom and two sides; the top has a sealing flap g.

Tt will be seen from inspection of Figs. 1 and 2 how the end and body blanks go together. The fastening flaps f fitting around the sides and bottom and being secured thereto by a line of wire stitches7t. However, no claim is made in the present application to this form of body buildin as the same has been described and claime in my prior applications No. 514,7 88 and No. 541,673. Furthermore, the specific form of the body construction has nothing to do with my im7ention which resides entirely in the top construction.

Now, by comparing Figs. 2 and 3, it will be Seen how the top construction is made efi'ective. The two sealing flaps g are turned in as is also the narrow cover flap d. The wide cover wing c is then folded down and a blade anvil a: is inserted over the cover fiap and under the sealing flaps and the cover wing. The stitches 1, 2, 3, 4, 5 are then taken. The anvil is then shifted to the v opposite side of the case and stitches 6 to 10 inclusive, taken. The anvil may then be inserted at either of the two corners of the relatively long case and short anvil, nit is desirable to begin the sealing of the cover wing and cover flap at the center as shown in Fig. 8, then reverse the case and work in.

again from the'center as shown by stitches to 18 in Fig. 9. However, each end of this line of stitches will go through only two thicknesses as shown in Fig. 10.

Itwill be obvious that any of the flaps or all could be on the outside of the cover wing and sealed in this way, and I desire it understood that the claims are to be read A to cover both ways.

-What I claim is:

1. The method of sealing a three-blank flush-end shipping case in which the end blanks are provided with sealing flaps and the side walls are provided one with a cover wing covering substantilly the entire widthof the case and the other side wall with a relatively narrow cover flap, which method comprises the insertion of a blade anvil under the large cover wing and one of the sealing flaps, and the driving of metallic fasteners to fasten the cover wing along one end tosuch sealing flap, then placing such anvil under the sealing flap at the opposite end and driving metallic fasteners through the large cover wing to fasten the cover wing at the other end, then the insertion of such anvil under the relatively narrow cover flap and driving metallic fasteners along the remaining edgeof the cover Wing to com- .plete the sealing of the box.

2. The method of sealing a three-blank flush-end shipping case in which the end blanks are rovided with sealing flaps and the side wal ls are provided one with a. cover win covering substantially the entire Width of't e case and the other side Wall with a relatively narrow cover flap, which method comprises turning in the sealing flaps and the narrow cover flap, and then folding down the large cover wing over such sealing flaps and cover flap, the insertion of a blade anvil in atthe side of the case over the cover flap and stitching first one end of the cover wing to the underlying seal1ng flap, then the other end of the cover wing to the underlying flap, then the insertion of the blade anvil under the narrow cover flap and the stitchingof the third edge of the cover wing to such cover flap to complete the seal ing of the case.

3. The method of sealing a three-blank flush-end shipping case in which the end blanks are provided with sealing flaps and the body blank is provided with a cover wing and cover flap, which method com prises the insertion of a blade anvil under the large cover wing and one of the sealing flaps, the driving of fasteners to fasten the cover wing along one end to such sealing flap, then placing such anvil under the sealing flap at the opposite end and driving fasteners through the large cover wing to fasten the cover Wing at the other end, then the insertion of the blade anvil and clinching metallic fasteners thereon driven through the cover flap to secure the third edge of the cover wing and complete the sealing of the case.

In testimony whereof I aflix my signature.
